WINDOW-SCREEN HANGER.

Specification of Letters Patent.

. Patented Feb. 27, 1912.

Application filed April 27, 1909. Serial No. 492,569.

To all whom it may concern Be it known that I, LoUIs A. Brrronr, a citizen of the United States, residing at Sterling, \Vhiteside county, Illinois, have invented certain new and useful Improvements in IVindow-Screen IIangers,of which the following is a specification.

hIy invention relates to hangers or fasteners for window screens and the like and the object thereof is to provide a simple and efficient device of this character possessing advantages not only in actual use but also in the operation of applying or installing the window screen and the like in place, as will be apparent from the description here inaftcr given.

In the drawing, Figure 1 is a perspective of a window casing and a screen held suspended and in place by means of the fasteners or hangers of my invention. Fig. 2 a perspective on a larger scale illustrating one of the fasteners or hangers in the act of attaching one member thereof to the other; Fig. 3 a view similar to Fig. 2 but showing an advanced stage of the engagement of the two members of the fastener or hanger; Fig. 4 a section on the line t-1l of Fig. 1 but on a much larger scale; and Fig. 5 a perspective of the upper member of the hanger or fastener.

Referring to the present embodiment of my invention, I prefer to use the fastener or hanger in connection with window screens and in the present instance I have shown the same applied to a window screen A running the full length of the window casing or frame B, although of course my invention is not to be limited to such particular construction or to window screens alone. As shown in Fig. 1, the window screen is suspended from and held fastened at its upper end by means of the two fasteners or hangers each of which consists of two separate members C and D having the peculiar construction and interlocking connection now to be described.

The member C is secured in suitable manner, as by means of screws C, to the upper cross rail B of the window frame and is provided with a hook or tongue 0 extending from its lower edge and projecting upwardly and outwardly, the curvature or inclination of such tongue being such, as hereinafter explained, as to properly cooperate with the other member ID.

The member 1) consists of a flat portion (Z, the outwardly curved intermediate portion 1] and an outer straight flange portion (Z said flat portion (Z being secured to the cross rail A of the window screen in suitable manner, as by means of the screws 1 The curved or intermediate portion 1) is pro vided with an aperture or opening 4 which of a size to admit the tongue c of the fastener or hanger melnber C, as clearly indieated in Figs. 2 and 3. Moreover, the flange portion (F has the same inclination as the outer end of the tongue P, so that when the two members of the fastener or hanger are in engagement their adjacent meeting faces are complementary. as shown in Fig. 4. As shown in Fig. 2, the opening (Z at its upper portion is rounded to correspond with the rounded free end of the tongue 0, which represents the preferred construction because it enables the opening to be made of a minimum size to thereby preserve the strength of the member or plate I). The flange portion (1 extends a cxmsiderable distance beyond the slot and in a direction at a slight angle to the attaching portion (Z of the member I). As a result of this construction and the outwardly curved portion in which the slot located by inclining or swinging the screen outwardly a sufiicient distance the flange can be brought to bear upon the stationary member of the hanger and the slot thereby removed a sullicient distance from the stationary member to facilitate extrication of the hook from the slot, and by somewhat: further tilting the screen as it is drawn backward the flange so spaces the slot from the hook that the latter may be-readily passed thercover.

In practice, the window screen is held outwardly at its lower end in the manner indicated in Fig. 2 and the same is slid upwardly between the opposite vertical sides of the window casing, whereupon the inner face of the flange portion (Z will contact the outer face or surface of the tongue 0 in respect to each hanger or fastener, with the result that upon further upward movement the window screen will be automatically forced outwardly to a slight extent but not suflicient to cause the upper end of the window screen to clear the space between the opposite vertical sides of the window casing. In this operation the flange portion (Z of each fastener or hanger slides upwardly and outwardly upon the tongue 0 of each fixed member 0 and after a sufiicient movement, that is when the opening (Z is presented, the member (Z will hook over the tongue so that when the window screen is now brought to a vertical position the complementary faces of the flange portion (Z and the tongue 0 will fit and cooperate with each other in the manner shown in Fig. I. It results from this construction and arrangement that engagement between the hanger or fasten-er members is conveniently and automatically brought about and that after engagement the upper end. of the window screen is firmly held inwardly in place within the window casing, said complementary surface causing a tendency of the window screen to press inwardly rather than outwardly, as will be readily understood from an examination of Fig. 4 of the drawing. hIy invention re lates solely to said fasteners or hangers and does not concern the means, if any are desired, for holding the lower end of the window screen in place, the same being either held permanently as by means of screws or in such manner as to be swung open it desired, the fastener permitting either method to be adopted.

I claim:

1. In a device of the class described,

hanger having a hook member G having an attaching plate, a slot member I) having a lip or flange extending a substantial distance beyond the slot to contact with the attaching plate for the hook member and thereby hold the slot away from the same when the screen or sash is swung outward beyond the normal to remove it from the hooks.

2. In a device of the class described, a hook member C having an attaching plate and an inclined portion 0, a slotted member D having a lip or flange extending a substantial distance beyond the slot to contact with the attaching plate for the hook member and thereby hold the slot away from the same when the screen or sash is swung outward beyond the normal to remove it from the books. 7

3. In a device of the class described, a member G having an inclined hook portion 0, a. slotted member D having a correspondingly inclined flange portion (Z adapted to engage with the inclined portion 0 whereby the screen is normally pressed inwardly against the window frame" at. In a device of the class described, a hook member C having an inclined hook portion 0 and a securing plate, a slotted member having a securing plate and a. correspondingly inclined flange member (Z together with an outwardly curved intermediate slotted portion cl.

5. A device of the class described comprising two engaging plates, one of which is adapted to be secured to a. window frame or the like and which is provided with an upwardly and outwardly inclined hook with a substantially straight under surface, and the other of which is adapted to be secured to a. screen or sash and which is provided with an upwardly and outwardly inclined portion having a slot to receive the hook and also having at its free end and beyond the slot a flange adapted to bear against and slide freely upwardly along said surface of the hook until the latter engages said slot.
